LOS ANGELES (AP) â€” Santa Barbara Sheriff’s deputies checking on Elliot Rodger weeks before he killed six college students were aware of but didn’t view disturbing videos that prompted calls about his well-being.

The sheriff’s office says Thursday that four deputies, a police officer and a dispatcher in training were sent to Rodger’s apartment April 30 after being informed by the county’s mental health hotline that Rodger’s therapist and mother were concerned about videos he posted online.

They questioned him for 10 minutes and then briefed Rodger’s mother by telephone before having him speak to her directly. They found him shy, timid and polite. He told them he was having trouble fitting in socially in Isla Vista and the videos were a way to express himself.
